…After 25 min of stimulation, frequency-tuned to individual brain network dynamics, we observed a preferential increase in neural synchronization patterns and the return of sender–receiver relationships of information flow within and between frontotemporal regions. The end result was rapid improvement in working-memory performance that outlasted a 50 min post-stimulation period.

This study further demonstrates the importance of electrical waves in brain functioning. It targets working memory decline in older adults but similar improvements were found in young adults already experiencing memory deficits.

“We showed that the poor performers who were much younger, in their 20s, could also benefit from the same exact kind of stimulation,” Reinhart says in a statement.

Incidentally, Buddhist mindfulness practice can greatly enhance working memory while also adding a metacognitive component to it in circumstances that would not otherwise normally call on metacognition.

FIML practice does something similar in that it adds a layer of psychological and linguistic mindfulness to working memory during acts of interpersonal communication.
